17.6.3 Weibull Fit

Contents

Introduction

There are three kinds of methods to do survival analysis: a non-parameter method, a semi-parameter method, and a parameter method. Weibull fit is a kind of parameter method to analyze the relationship between the survival function and failure time.

From the table of Analysis of parameter estimates, you can determine the relationship between the survival function and the failure time. The value of the survival function can be obtained from the following equation:
